I was asked by a friend if I could point him to any helpful online tools for analyzing stocks that would take the data provided by say Yahoo financial. He is looking for an easy way to summarize the data in different ways than what are provided on the site. I know that at least Yahoo Financial allow for downloading the data to a spreadsheet. The things he wants done can be done there but it requires a bit of building the formulas each time. I know there are tons of programs out there to aid in stock analysis. Can anyone point me to one that would seem to fit the bill and be relatively straightforward and simple to use? I am not really into the investment analysis scene much so I don't have a quick answer for him.
